W
The inventor of the electrical generator and the electrical transformer.
Who is Michael Faraday?
A small "package" of light energy that acts like a particle
What is a photon?
When materials allow light waves to pass through, but scatters the light waves as they pass.
A buildup of electrical charges within or on the surface of a material.
What is Static Electricity?
The amount of charge that travels past a fixed point in an electrical circuit each second
What is Electric Current?
States that light is a wave and not a particle.
What is Wave Theory?
Materials through which electrons can easily flow.
What is Electrical Conductors?
States that a beam of light behaves the same as a stream of particles, as they all moved in the same direction
What is Particle Theory?
Have the shortest wavelengths and highest frequencies in the electromagnetic spectrum
What are Gamma Rays?
States that light can travel through any region of space, regardless of what occupies that portion of space.
What is Quantum-mechanical Theory of Light?
The force a magnet exerts on another magnet, on metals or on moving charges.
What is Magnetic Force?
Electromagnetic waves with wavelengths just shorter that the microwaves
What is Infrared Light?
The ability of a material to impede the flow of charge.
What is Resistance?
What is an Electromagnetic Wave?
What happens when electrons are emitted from a material that has absorbed electromagnetic radiation
What is the Photoelectic Effect?
Materials that become permanent magnets.
What are Ferromagnetic Materials?
A small "package" of light energy that acts like a particle.
What is a Photon?
Charging an object without direct contact between the object and a charge.
What is Charging by Induction?
A circuit that does not have a complete connection between the two sides of the power source. As a result, current does not flow.
What is an Open Circuit?
Charging an object by allowing it to come into contact with an object that already has an electrical charge.
What is Charging by Conduction?
A circuit that allows devices to work independently from each other.
What is a Parallel Circuit?
Materials in which electrons cannot easily flow.
What is Electrical Insulators?
A cluster of many atoms that have their magnetic fields aligned and so act as a magnet.
What is Magnetic Domain?
Charging an item by rubbing two items together where one transfers electrons to the other.
What is Charging by Friction?
Current that flows from the positive side of the battery to the negative side.
What is Conventional Current?
